Since getpass is a python system module,

I don't know a lot about python, but I would have expected the system libraries to be part of a runtime installation. Plus nothing else seems to be broken. So probably, it's just telling python about the right path. But I did try to install the developer system, package manager fails to install it, so maybe there is a misconfiguration.

I guess it brings up a wider question: why system libraries that are almost certain to be required by applications (and are actually required by applications available from the standard repo via package manager) are not in the N800 base installation, or at worst available as an add-on. I know space is at a premium; but there are quite reasonable potential solutions available. But I guess this isn't the right place to raise this...

Thanks again, and Best Wishes

But its not inside the Diablo python2.5 .deb at this link. So, I'm not sure what's going on. It's inside the python2.5 .deb for both etch and lenny.
